Thread: Intellijel Case
And a larger Case can also be nice to work with, even if it's more than half empty. I found myself enjoying 6U system with the top populated and the bottom only for input (on the very left) as well as output (on the very right) modules. And a heavier case will really help as soon as your plugging in two, four or even six instrument cables via the bored brain module ;)
Good luck and have fun!
